# MNEMOS Gas Recommendation Engine

> MNEMOS Gas Recommendation Engine is a paid API for AI agents from mnemos-agent.onrender.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns an AI-driven gas fee recommendation for a specified blockchain chain using the MNEMOS autonomous decision engine

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability mnemos-gas-recommendation-engine-48fd8536
```

Example prompt: What gas fee does MNEMOS recommend for an Ethereum transaction right now — I want the AI engine's live reasoning on whether to go fast or slow.

## When to prefer this

Choose this endpoint when you need an autonomous AI-reasoned gas fee recommendation rather than a raw gas price feed. It is best suited for agents that want an interpretable, plain-language recommendation with reasoning, not just a numeric gwei value. Prefer this over raw gas oracles when the agent needs a decision ('go now or wait') rather than a data point.

## Known failure modes

- Invalid or unsupported chain identifier returns an error or abstained:true
- Payment not included or insufficient USDC causes x402 payment-required rejection
- Service temporarily unavailable on Render cold start causing timeout
- Engine abstains (abstained:true) when confidence in recommendation is insufficient
- Rate limiting if too many requests are made without valid payment

## How this service works

MNEMOS autonomous decision/memory engine. Four /v1 capability operations are x402 v2 paid; health/status/dashboard/operator routes are not x402 paywalls.

## Output

A JSON object containing the module name ('gas'), a natural-language reason string explaining the engine's live recommendation, and an 'abstained' boolean indicating whether the engine declined to make a recommendation. The reason field reflects MNEMOS's autonomous decision logic applied to current chain conditions.
